So I have a Sprint 7130e, and I downgraded to the Alltel OS so I could enable the other carrier themes. Bell and VZW work fine, but the ones for GSM (Vodafone, O2, etc.) do not. They show up, but when I enable them, I don't know what type of signal I have because for some reason, it can't show 1x, 1X, or 1XEV.
